WIRE-CLOTH FOR PAPER-MACHINES.

- SPECIFICATION forming part of Letters Patent No. 709,228, dated September 16, 1902.

Application filed June 13, 1902. Serial No. 111.455. (N model.)

To all whom, it may concern Be it known that I, RUDOLF KRON, J r., a citizen of the Republic of Switzerland, and'a resident of Golzern, in the Kingdom of Saxony, German Empire, have invented new and useful Improvements in Metallic Wires or Sieves for Producing Small Bands or Ribbons of Paper-Pulp, Cellulose, and the Like, of

which the following is a specification.

This invention relates to improvements in metallic wires or sieves to be used in papermaking machines for the production of small hands or ribbons of paper-pulp, cellulose, or any other analogous material.

It is known that metallic wires or sieves have been divided lengthwise for the above place byapplying upon the wire or sieve strips of any suitable material, such as strings, wax

strings, or the like.

Now my invention consists in dividing the metallic wire or sieve in the weaving operation lengthwise by metal strips at a certain distance apart from each other, and dividing 2 5 the space between such metallic strip by metallic subdividing-threads. In producing paper on such metallic wire or sieve in the papermaking machine the breadth of the paper between the two metal strips is divided by the 0 said threads into a series of small ribbons or bands, the fibers of which protruding from the sides willform beards by which the small ribbons or bands stick or adhere together and may be afterward handled together in the 5 above-named breadth, but which small rib- .bons or bands may hereafter be easily separated in the same manner as paper perforated into strips may be separated. The small ribbonsorbandsofpaper-pulp or the likematerial 40 thus produced are of a regularity not arrived at hitherto, of very neat appearance, and by {)heir coherence to be handled as a broad and.

The metallic wire made according to my in- 5 vention may be used in paper-machines havpress upon the wet pulp while running with the sieve. a

In the annexed drawings, Figure 1 is a plan view of part of my metallic wire or sieve, and Fig. 2 is a cross-section of same.

The wire or sieve is divided lengthwise by metallic strips a, woven into the wire or sieve, and in the space between said strips a metallic threads I) are woven also lengthwise spending to the distance between two threads b b. Each pair of such two threads form a channel between themselves into which the pulp deposits and is formed in the regular way of paper-making into a small ribbon or band; but as some of the fibers in such channel will cover in some way a thread b from both sides each small ribbon or band will be in some way connected to its neighbor ribbons or bands, so that the entire breadth between vtwo strips a a adhere together; but this connection is such one that the breadth may afterward be separated band by band in an easy manner. The channel between two threads I) b may be a flat one. Such channel, however, may be formed so as to be of triangular or semicircular cross-section, so that the ribbons or bands formed in said channels will adapt or nearly adapt the form of said channels. a

The bands or ribbons are intended to be used as raw material for being spun into threads for weaving purposes, or the bands or ribbons-may be used as packing material or as cushion material, or, if theyconsist of cellulose,they may be used for nitrifying purposes.

I claim- A metallic wire or sieve for paper-making purposes into which wireor sieve metal strips are woven in longitudinal direction to form breadth of paper and betweensaid strips metallic threads are woven in longitudinal direction to divide said breadth into small bands or ribbons.

In testimony that I claim the foregoing asmy invention I have signed my name, in presence of two witnesses, this 30th day of May,
